COOFANDY Men's 2 Pieces Cotton Linen Set Henley Shirt Long Sleeve and Casual Beach Pants Summer Yoga Outfits

Does this actually have any linen? It says 98% cotton and 2% polyester? I don't see how there is any linen in them but maybe I'm mistaken

Should I get a large? 6 feet tall, 185 lbs. My pants are usually 35X30.

i need 34 waist is large ok

Husband is 6ft 240lbs wears xxl, waist is 38” if it’s true to size do i go with the xxl or with the recommended sizing guide?
